Technical Field
[0001] This utility model belongs to the field of seeder technology, and in particular relates to a soil scraping device for a press roller. Background Technology
[0002] In the field of agricultural machinery, seeders are commonly used equipment for evenly sowing seeds into the soil. However, during the sowing process, the rollers often stick to soil, resulting in poor soil covering after sowing and affecting seed germination and growth. To solve this problem, a device is needed that can effectively clean the soil layer adhering to the surface of the rollers.
[0003] Existing cleaning devices typically use tools such as scrapers or brushes to clean the surface of the press rollers, but these tools have several problems. First, scrapers or brushes offer significant resistance when cleaning press rollers, making them ineffective for cleaning V-shaped press rollers. Second, these tools have a short lifespan, are prone to wear and damage, and require frequent replacement, increasing operating costs. Furthermore, the installation and adjustment of these tools are cumbersome, making them inconvenient to operate and maintain.
[0004] Therefore, it is necessary to design a soil scraping device for the press roller that is simple in structure, has good cleaning effect, long service life, and is easy to install and adjust, so as to improve the working efficiency and sowing quality of the seeder. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Specific Implementation Example 1:
[0027] Please see Figure 1-4As shown, this utility model is a soil scraping device for a press roller, including a fine-tuning base 2 mounted on a press roller frame 1. A wire scraper 3 is mounted on the fine-tuning base 2. The wire scraper 3 includes a support frame 31 mounted on the fine-tuning base 2, a steel wire 32 mounted on the support frame 31, and pre-tightening terminals 33 for pre-tightening both ends of the steel wire 32. The press roller for the seeder is mounted in a V-shape on the press roller frame 1. The steel wire 32 mounted on the support frame 31 in the wire scraper 3 is also V-shaped. During installation, the steel wire 32 is flush with and close to the upper end of the press roller. The steel wire 32 cuts the soil adhering to the surface of the press roller to reduce the impact on the soil covering and compaction after sowing.
[0028] The fine-tuning base 2 includes a guide plate 21 and two shank bolts 22. Two first threaded through holes 211 for mounting and positioning are respectively opened at both ends of the guide plate 21. A rectangular block 212 is fixed to the middle of each end of the guide plate 21. A second threaded through hole 213 is opened on the rectangular block 212 for threaded connection with the shank bolts 22. The two shank bolts 22 on the fine-tuning base 2 allow for fine-tuning and positioning of the wire scraper 3 installed inside, facilitating the adjustment of the wire 32 in the wire scraper 3 to the optimal position for cutting the soil layer on the surface of the press roller.
[0029] In order to fix the shank bolt 22 after adjustment, a first locking nut 23 is threaded onto the shank bolt 22, and the first locking nut 23 is located on the outside of the rectangular block 212.
[0030] The support frame 31 includes a support body 311 with a V-shaped lower opening. An end support plate 312 is vertically fixed to each end of the support body 311. Two cylindrical rods 313 are symmetrically fixed to the middle of the inner wall of the support body 311. A ring 314 for threading a steel wire 32 is fixed to the lower end of each of the two cylindrical rods 313. An externally threaded cylinder 315 is fixed through each of the two end support plates 312. A pre-tightening terminal 33 is threadedly connected to the externally threaded cylinder 315, and the end of the steel wire 32 passes through the externally threaded cylinder 315 and is fixed to the pre-tightening terminal 33. The portion of the steel wire 32 located inside the support body 311 is parallel to the two side walls of the support body 311. A guide slider 316, which slides in cooperation with the guide seat plate 21, is fixed to one side of the middle of the support body 311. The support frame 31 has a stable overall structure, which is conducive to the installation of V-shaped steel wires 32 on it. The diameter of the steel wires 32 is no more than 0.5mm, which ensures the simultaneous cutting and cleaning of the soil layer adhering to the surfaces of the two pressing rollers.
[0031] The pre-tightening terminal 33 includes an internally threaded cylinder 331 threadedly connected to an externally threaded cylinder 315, and a rod 332 fixedly connected to the end of a steel wire 32. The free end of the internally threaded cylinder 331 has a slot 333 that mates with the rod 332. A second locking nut is threaded onto the externally threaded cylinder 315. By rotating the internally threaded cylinder 331 in the pre-tightening terminal 33, the steel wire 32 mounted on the support frame 31 can be tightened. After tightening the steel wire 32, the second locking nut is rotated to position the internally threaded cylinder 331, ensuring the steel wire 32 remains taut. The entire adjustment process is quick and convenient.
